It provides interface details and service implementation details.

• A. WS-Security
• B. UDDI
• C. Service Description
• D. RESTful

Answer: (C)

Understanding how to interact with a service requires a contract that specifies what you can do and how to do it. A Service Description provides exactly that: the interface details—what operations exist, what messages are exchanged, and the data types involved—and how to access them, including binding to a protocol and the endpoint address. This contract guides both clients and the service implementer on how to invoke the service, even though it doesn’t reveal the internal business logic. WS-Security focuses on securing messages, not describing how to interact with the service. UDDI is a registry for discovering services, not detailing how to call a specific one. RESTful describes an architectural style for designing services, emphasizing resources and standard HTTP methods, rather than a formal contract for a particular service’s interface.
